There’s (almost) an app for that:
I’ve seen the future and it is math less and it is awesome and it is this PhotoMath app that solves math problems just by pointing your phone’s camera at them. It’s like a cross between a text reading camera, a supremely sophisticated calculator and well, the future. Point and solve and never do math again.
We’re all going to get a lot stupider after this thing comes out next year, aren’t we?
